Question about reading from files
we are learning about reading from text files in my class. I have a list of student names along with their grade on a history test. I need to find the class average.
Here is my code so far:
Code:
// File: Gradeclass.cpp
// Class: ITCS 1214 TR 5pm
// Purpose: To classify student's grade by
// Satisfactory, Unsatisfactory, and Outstanding.
#include <iostream>
#include <fstream>
int main()
{
string name_1[10],
name_2[10];
int test_score[10],
class_total = 0,
index;
float grade[10],
class_average;
index = 0;
ifstream in_file;
in_file.open("History_Exam1.txt", ios::in);
for(index = 0; index < 10; index = index + 1)
{
in_file >> name_1[index];
in_file >> name_2[index];
in_file >> test_score[index];
}
for(index = 0; index < 20; index = index + 1)
{
// this is where I am stuck
class_average = test_score[index]
For that last part, I need to find the class average so what I basically need to know is how to write the sum of the test scores so I can divide it by the number of students.
Thanks in advance for the help.
